title: [Photodamage to spores of Fusarium fungi, sensitized by protoporphyrin IX].
abstract: The influence of photodynamic action with protoporphyrin IX as a sensitizer on the state of the components of hydrated spores of Fusarium fungi and germination of conidia in growth medium was investigated. It was shown, that protoporphyrin IX in micromole concentrations sensitizes the photooxidation of proteins and lipids from hydrated spores of Fusarium poae and Fusarium culmorum under illumination of their suspensions in doses of 50 - 200 kJ/m2. It was found that the photosensitized oxidation of cellular components leads to the disturbance of conidium membrane permeability and inhibition of spore germination during their subsequent cultivation in growth medium.
